3 FUNCTION
No. Name Function
1 Compressor
Increases pressure for the refrigerant and provides driving force for
circular flow of the refrigerant as a main driving component.
2 Four-way valve
Reverses flow direction of the refrigerant when the system
switches between the normal heat up mode and defrosting mode.
3 Water tank
Provides heat exchange channel for refrigerant and water and
stores hot water for daily use.
4
Electronic expansion
valve Speeds up high-pressure and high-temperature refrigerant and
reduces pressure and adjusts the circulation amount of coolant.
5
Finned tube
exchanger
Provides heat exchange channel for refrigerant and air.
6 Fan motor
Enhances heat exchange on the air side of the finned tube
exchange and provides a low-temperature heat source
continuously.
7 Filter
Filters impurities in refrigerant to protect components with small
diameter.
